To connect to QuickBooks Time, you can use either a DSN or an ODBC connection string. Both of these methods use the sql package's Open function.

Connect to a DSN

To connect using a DSN:

db, _ := sql.Open("odbc", "DSN=CData TSheets Sys;")
defer db.Close()

Provide a Driver Connection String

To connect using an ODBC connection string:

db, _ := sql.Open("odbc", "DRIVER={CData ODBC Driver for QuickBooks Time};OAuthClientId=myclientid;OAuthClientSecret=myclientsecret;InitiateOAuth=GETANDREFRESH;CallbackUrl=http://localhost:33333;;")
defer db.Close()
